Lambda Legal said Thursday it has a federal lawsuit on behalf of three same-sex couples who seek the freedom to marry in their home state of Indiana. The federal lawsuit was filed by Lambda Legal on behalf of three lesbian couples from Whitestown, Chesterton and Munster. The suit, filed on behalf of of three lesbian couples from Whitestown, Chesterton and Munster, argues that the couples’ equal protection rights are being violated because they can’t marry in Indiana and the state won’t recognize same-sex marriages performed elsewhere. The suit was filed on Monday in the U.S. District Court for the Southern District of Indiana; a similar lawsuit was filed last week by four couples from southern Indiana.

What a turnaround from a couple months ago, when it looked like a constitutional ban might be on the ballot in Indiana in November.
